XT926 last running was 4.1.1 stock new phone HD. Rolled it back to 4.0.4 using (Droid Razr HD Utility 1.10) Now im Stuck at AP Fastboot Flash mode. Error of ( No PIV block in SP for system piv validation failed (system) Fastboot reason: Boot failure)
I can get into Boot mode selection and get into AP fastboot. when i run Utility it starts to install runs for a bit comes to Press Any Key When The Screen Comes Back On. And it does. Press enter and runs/writes the rest of program. Near the end of install i see Failed status read <Unknow error>> (invalid argument) Its happens at devtree/modemst1/modemst2/ then it stops at Do i want to wipe Data that it recommened . I say yes. Gets to end says you are now on stock 6.6.25- ICS 4.0.4. Phone does not reboot. It stays on the AP fastboot mode screen.
NOw what????
